Chemical Structure

6-Hydroxynorgestrel CAS 40915-05-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Hydroxynorgestrel.

6-Hydroxynorgestrel (CAS 40915-05-7) is a high-purity analytical reference standard with the molecular formula C21H28O3 and a molecular weight of 328.45 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, 6-Hydroxynorgestrel is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 6-Hydroxynorgestrel under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
